Synthesis of substituted phenols by directed ortho-lithiation of in situ N-silyl-protected O-aryl N-monoalkylcarbamates

Kauch, Matthias,Hoppe, Dieter

, p. 1736 - 1746 (2007/10/03)

A simple, high-yield procedure has been developed for the ortho-lithiation and subsequent ortho-substitution of phenols by a manifold of electrophiles. N,C-Dilithiation of O-aryl N-monoalkylcarbamates proved to be impossible due to a cleavage reaction of
